Heatblast, Four Arms, Diamondhead, and XLR8 are all from the original show. Including the other shows, Alien X is more popular than Four Arms, Diamondhead, and XLR8.

Alien X is also the most plot-heavy alien within Ben's arsenal. It makes sense it'd be the most popular.

Also, fuck the reboot and omniverse. Both of them ruin Ben 10 is more ways than I can imagine.
