I don’t remember exact years, but I’ll try to be as detailed as I can.
First game I believe was on one of the Sega consoles in the mid 90s OR it was SNES. It was a side-scroller platformer game and while I don’t remember much, I remember the main character was red and he used throwing stars for weapons. As far as I know, there’s no Sonic ninja games in that era.
Second game was either on PS1 or 2, but I’m leaning towards PS1. It was a bicycle racing game where the cast of characters was pretty varied. One character was a skeleton and one was a Frankenstein. Sadly, that’s all I know.
