  If Wikipedia only creates articles based on outside sources, the how come there are articles for pretty much every Inuyasha characters, even some that haven't appeared in more than 1-2 episodes. Compared to that I think Ike definitely deserves an article. For more in-universe support, there is also the fact that Ike is the only recuring main character after Marth (Roy's cameo at the end on FE7 doesn't count). In addition, Ike was revealed to be playable in SSBB so many people would be curious who he is. Of course I'm not saying we should create his article specificaly for that reason, but it adds to the other reasons. Since Ike's information is spread so much throughout the articles it is inconvenient to check what he did in the prequel and the sequel. This would organize information and make it much more convenient to look up info.
