What game is Ike and Marth from?

Answer 1

Marth and Ike are both in the Fire Emblem series, but are not in the same game.

Marth is in:

Fire Emblem: Ankoku Ryuu to Hikari no Tsurugi

Fire Emblem: Monshou no Nazo

Fire Emblem: Shadow Dragon

Fire Emblem: Shin Monshou no Nazo - Hikari to Kage no Eiyuu

while Ike is only in:

Fire Emblem: Path of Radiance

Fire Emblem: Radiant Dawn

Both are also in Fire Emblem Awakening but as add on content

Answer 2

Marth and Ike are from the same series ‘Fire Emblem’, but are from different games.

Marth Lowell, the first FE protagonist was seen in Shadow Dragon and the Blade of light as the hero king of Altea. Later on in the series, he was also in Mystery of the Emblem, and in the Xenolauge ‘Champions of Yore’ in Fire Emblem Awakening etc.

Ike was the main protagonist of Path of Radiance, and was seen in Radiant Dawn. Ike is also seen in the Xenolauge of awakening and is a DLC in the actual FE Awakening game.

If you don't count the spinoffs and the crossovers, the two lords are not seen together in a game. Fire Emblem Heroes, Code Name: STEAM, and Super Smash Bros are one of the few games in which put Marth and Ike together. Code Name: STEAM and Fire Emblem Heroes are two spinoff games made by Intelligent Systems (The Creators of FE), while Super Smash Bros Brawl and Super Smash Bros Ultimate are two crossover games created by Masahiro Sakurai (who, fun fact: created the two characters Kirby and Pit.)

Though these characters arent canonically together, I do hope that they make a canon game in which they introduce them together (or even with other FE protagonists like Roy, or Kamui, or Erika, etc.) Hope this helps. ^^
