I think there was an early version of RA1 that had Omnivore and Gammaraze in it, but soon after its release they released a new version that replaced them with Triclops and Gammaraze II along with other updates. Don't ask how I know that, I just seem to remember it.
If so, then 090901 must have got RA1 right when it was first released so he got the early version.
