I cant model these vehicles but if there is someone who could mod them they should be splitted into these 3 categories :

1)Titans
titans from Titanfall

2)Knightmare Frames
those titanfall size robots with a weird bulging cockpit from CG

3)Mobile Suits
Biggest of all, these were mechs from the Gundam Franchise, the best-selling mech models where Transformers are 2nd
