Because I've heard Cloud's English voice in Kingdom Hearts for a decade before he got into Smash. And honestly, I find foreign languages weird. I was confused when I first heard Marth's Japanese taunt in an online match in Brawl. And without Steve Burton's voice, I wouldn't hear Cloud's funniest battle quote from Kingdom Hearts: "MOVE!" I always found it weird how he keeps shouting "MOVE!" when attacking Sora. Though, his Sonic Blade attack wasn't included in Smash. Eh, lame battle cry anyway. While I got that Marth spoke Japanese because his games weren't dubbed in English yet, hearing Cloud in Japanese when I'm used to his English voice felt so weird to me.
