Ike

Ike is the protagonist in two games of the Fire Emblem series, debuting in Fire Emblem: Path of Radiance, the series' ninth installment. In his home series, Ike is the leader of the Greil Mercenaries, who are drawn into two wars spanning the continent of Tellius. With the help of his companions, Ike acquires the sacred sword Ragnell and brings peace to Tellius, ending hostilities between its inhabitant beorc and laguz races in the process.

He appears as a playable fighter in the Nintendo-crossover fighting game, Super Smash Bros. Brawl, and returned for its successors, Super Smash Bros. for Nintendo 3DS / Wii U and Super Smash Bros. Ultimate. Ike is the third Fire Emblem character to appear in the Super Smash Bros. series, after Marth and Roy. Ike is a very powerful fighter - one of the strongest, but as a downside, he is quite heavy and slow.

Super Smash Bros. Brawl
Ike is a playable character in Super Smash Bros. Brawl, using his appearance in Fire Emblem: Path of Radiance. He fights using the two-handed longsword Ragnell, which gives his attacks power and range, but as a result he is slower and heavier than most characters. Ike was not originally intended to be in the game from the start; instead, Masahiro Sakurai had created a template for a slow but powerful swordsman. As he also wanted to include a new Fire Emblem character, it was decided that Ike, in addition to being the protagonist of the latest games in the Fire Emblem series at the time, would be a good fit for the concept. Ike is voiced by Jason Adkins in English, and by Michihiko Hagi in Japanese, his respective voice actors since the release of Fire Emblem: Path of Radiance. This also makes him the first Fire Emblem character in the series to be given an English voice actor.

Ike's neutral special move is Eruption, in which he plunges his sword into the ground to create an explosion. His side special move is Quick Draw, which has Ike charge a sword slash that sends him directly forward. His up special is Aether, in which Ike throws his sword into the air and slams back into the ground. His down special move is Counter, which has Ike deal a counterattack if he is hit. His Final Smash is Great Aether, which has him slash any nearby opponents into the air, where he repeatedly attacks them before slamming them back into the ground. Ike's stage entrance involves him appearing on the stage via warp magic.

Adventure Mode: The Subspace Emissary
Ike makes his debut in Adventure Mode: The Subspace Emissary near the end of The Battlefield Fortress. During the story, both Marth and Meta Knight fail to stop the Ancient Minister from carrying another Subspace Bomb to another location in the trophy world. Hope seems lost for the two, until, out of nowhere, the Ragnell sword begins hovering behind the Ancient Minister, and Ike continues to use Aether on the Subspace Bomb, breaking it and deactivating it, making the Ancient Minister flee. The three warriors continue through the wasteland, finally reaching the Ancient Minister, but are unable to do anything as he floated over a cliff.

The three continue to dash onwards through The Wilds, after seeing Galleom in its tank form. Galleom transforms into its main form after meeting the swordsmen. Ike, Marth, and Meta Knight face off against Galleom afterwords, and then continue into The Canyon. After Meta Knight had left the group after Galleom was defeated a second time, Ike, alongside Pokémon Trainer, Lucas, and Marth, are seen fighting many Primids, now with the Ice Climbers. The five "warriors" are then seen (Mario, Pit, Kirby, Link, and Yoshi) in the background, jumping off from a bluff to help fight off the army. After awhile, Ike, alongside many others, are flown into Subspace, where he and all others are turned into trophies. However, King Dedede, Ness, and Luigi recover him, and others (Kirby also helps afterwards). He and the others are then pitted against The Great Maze, and then the creature whom turned the heroes into trophies, Tabuu.

Super Smash Bros. for Nintendo 3DS / Wii U
Ike returns as a veteran fighter in Super Smash Bros. for Nintendo 3DS and Super Smash Bros. for Wii U. His design has been changed to be his appearance as a Hero in Fire Emblem: Radiant Dawn. While Ike's moveset is no different from the previous game, most of his attacks that use fire use blue flames rather than the red seen in Super Smash Bros. Brawl, referencing his blessing by the goddess Yune at the end of Fire Emblem: Radiant Dawn, during which his sword is cloaked in blue fire. Ike receives faster movement and attack speed, in exchange for his overall damage output being slightly toned down.

Super Smash Bros. Ultimate
Ike reappears in Super Smash Bros. Ultimate as a playable character, where this time, players can choose to play as his Fire Emblem: Path of Radiance or Fire Emblem: Radiant Dawn appearance. His voice also changes slightly depending on which appearance is used, which is provided by his voice actor from Fire Emblem Heroes, Greg Chun, replacing Jason Adkins from previous Super Smash Bros. installments. Ike benefits greatly from universal changes: his mobility is even faster, his short hop timing is greatly reduced, his aerials have less landing lag, his recovery is extended by the reintroduction of directional air dodges, and his offensive play is aided by the abilities to use any ground attack out of a run and use his aerials on ladders.

On a side note, as with several other returning fighters, Ike's (as well as Marth and Roy's) victory theme has been sped up compared to the previous installments.

Classic Mode route
Ike's Classic Mode route involves fighting characters in dark-colored alternate costumes (except if they are dark-colored by default). This represents his relationship with the Black Knight in his own games.

Snake's codec

 * Snake: This swordsman's gonna be tough to beat.
 * Colonel: Fighting Ike, eh, Snake? Ike is the leader of the Greil Mercenaries. He may look too refined to be a fighter... But he has one heck of a sword arm.
 * Snake: Yeah, he's swinging that two-handed sword around with only one hand. I don't even want to get near him.
 * Colonel: That's the holy blade of Ragnell. It's an extremely powerful sword. But don't forget, Snake, you're armed to the teeth yourself. To your opponents, you might just be their worst nightmare. The distance between you and your enemy is a crucial element in battle. Using that distance can give you an advantage against some enemies.
 * Snake: Yeah, I've got the same feeling...

Super Smash Bros. for Wii U

 * Pit: Does Ike look a little different to you? Maybe a little...tougher?
 * Palutena: Hmm...
 * Pit: His clothes look different, and his sword looks even more menacing.
 * Palutena: Yes, I suppose you're right.
 * Pit: And he definitely hasn't aged well.
 * Palutena: Well, compared to gods and angels like us, Ike is just a baby.
 * Viridi: I don't know how old you are, Pit, but you don't look like you've grown at all.
 * Pit: Oh, like you're one to talk! How old are you, anyway? Ten?
 * Viridi: A goddess never reveals her age, Pit.
 * Palutena: Break it up, you two. Back to Ike. He has a powerful side smash that he will send you flying, but that's also his weakness.
 * Viridi: He's very vulnerable at that time, so dodge it and strike back!
 * Pit: I claim this victory in the name of Skyworld! SKYWORLD! SKYWORLD!
 * Viridi: YEAH! SKYWORLD! SKYWORLD! SKYWORLD!

Super Smash Bros. Ultimate

 * Pit: It's Ike!
 * Viridi: There are two versions of Ike. The Path of Radiance version and the Radiant Dawn version.
 * Pit: Dawn? Radiance?
 * Viridi: He's basically either a mercenary or a hero.
 * Palutena: The two versions of Ike may look and sound a bit different, but his strength doesn't change at all.
 * Viridi: But one of them is three years older than the other. Shouldn't the older one be stronger?
 * Palutena: Yeah, you'd think the older one would have three more years of training under his belt.
 * Pit: Maybe he skipped three years of arm days.
 * Palutena: I somehow doubt that. Have you seen the way he swings that sword? One blow from that sword can do more damage than two of yours, Pit. Be careful.

amiibo

 * One of the main characters from the Fire Emblem series. Having fought in the Mad King's War, restored the fallen nation of Crimea, and taken on the Begnion Empire, Ike is rightly called a hero. He has the strength to back the title – his powerful blade makes him a match for any foe.

Super Smash Blog bio

 * Ike's side smash attack is extremely powerful, but it leaves him open, so you'll need to read your opponent's moves carefully. You can choose between his Path of Radiance and Radiant Dawn costumes.

Quotes

 * ''"Prepare yourself!"
 * "Aether!"
 * ''"Great... AETHER!"
 * "You're open!"
 * "Gotcha!"
 * ''"I fight for my friends."

Trivia

 * When Ike uses Aether to attack the Ancient Minister, he shouts "Great Aether."
 * If Ike grabs someone while he is a giant and does a pummel, the grabbed opponent instantly breaks free from the grab, regardless of their damage. This also happens if Ike grabs someone while tiny.
 * Ike's crowd cheer in the Super Smash Bros. series, "We like Ike," is a reference to the campaign slogan used by U.S. President "I like Ike."
