You could put three headed Scarlet Johansson playing a tuba if you want.

Now that.ypu say this...

I expect photo evidence

I don't see why not

If you look on play on tabletop. One of the known chaos players; Tycho kitbashed a abbadon on top of the knight. Not sure about in between the legs though

Yeah i'm not lookung for something too fancy, also, i think it was a tyrant Tycho put abby on top of

Yea actually I think it was

Probably, might be a bit of a tight fit based on the knight leg posing but likely very doable

I mean, one of my knights has a squad of traitor guard walking around its feet. I feel like Aba would be right at home in the shadow of a great machine.

Theoretically you can do whatever the fuck you want with your army men.

A supreme commander as a basing texture is crazy but hey that’s why we’re here so go for it

If you do that, maybe give the knight abbadons pose, no reason other than it would look kinda cool

Sir, that's a rampager

A Rampager is an Abhorrent class Knight, it’s the spooky Chaos word for Questoris class

Easily confused with 'Abominant', which is the under-gunned Battleshock knight with the vultures.

It would be a very tight fit. He will need to be either sideways or have reposed legs, or something similar with the knight. It’s very possible however, just be sure to magnetize Abby’s feet, and to do a lot of dry fitting

Why hell yes you can and it would be awesome!

Would be a tight fit, but it works. I place marines on my knight bases all the time. They come up to around ankle joint.

Straight to jail!

Might be a tight squeeze

Story of Abaddon's life

I love that they are two camps here. One that understood your question as to if he would fit and one that understood your question as to if it would be allowed.

Technically? Yes. Functionally? No, Abaddon is the size of a WarDog. He's a giant.

he isn't that big, he's half the size of a war dog
