Good! I'll make a riddle. It's of a character:

1. It lives in a land that has the look of the video-games from the 80s (such as Super Mario Bros.).

2. Despite the above, the only game where it appears was released after 1990.

3. The character is known to have difficulties in making friends... unless through computer (online).

4. Mario fights against him twice in the game, the 2nd time being optional.
