Thundercats,Silverhawks,Tigersharks
 

In the new thundercats series we saw that all of these are different species within the same kingdom.

All three of these toys where made in the 80s by the LJN toy corporation.

I recently purchased a mon star action figure from my local comic shop a couple months ago, and I got my vintage Thundercats out of storage and up on a shelf, I decided to put mon star up with my thundercats and call him part of my thundercat collection.

What are your guys opinion on this? I never had tigersharks but if i ever manage to find more silverhawks or tigersharks I will be putting them with my thundercats :)

Tigersharks fit in just fine. The Silverhawks toys were not made by LJN, who passed on producing them. They were actually made by Kenner and are a different style and scale than the Thundercats/ Tigersharks. Monstar should look pretty small with your Thundercats.
