The first one was very similar to Robot Wars, but instead of RC robots controlled by teams, it was CGI fighters controlled by one person at each side of the arena. There was a game of it on the PS 2 as well which I remember owning at some point.
The Second one was a CBBC show, again about CGI. But it was monsters that looked like they were made in a basic modeling program (I think they were actually) made by teams of kids, and the monsters automatically attempted to do challenges or beat others. It was set in a lab with all the kids in lab coats There was a downloadable kit you could get of the shows site that was the same one the teams in the show used and do the challenges yourself in it. Both were on around the same time in the early - mid 2000s I think.
