That is a rather vague question. There are many types of Mobile Suits. Mobile Suit is a humanoid mecha. There are: Ground based MS Aerial Water based ones although those tend to be mobile armor. Space ms there are GN based weapons in Gundam 00 transformable MS such as Zeta Gundam or Arios There are MS with Pyschoframes there are Mobile Dolls, controlled empty suits in Gundam Wing. These are all the possible types i can think of. This mite not count but MS that are meant to dock with a mobile armor, such as Exia/GNArms or the Denobium from the Gundam OVA and by extension Freedom/METEOR
