Trooster is the next step in the life cycle originating from his flying egg form “Distrooster”, with the in-between form being Trooster Jr. Some Distroosters fly over this new form, many being shocked and disgusted by what they see.
Having been abandoned by his earlier family of Distroosters, Trooster seeks to form bonds elsewhere. Trooster’s two big sagging “Memory Glands" store the spiritual information he absorbs from staring intently with a high degree of trust & Muskulls is the new target of this trust.
Having Trooster on your side means you have a loyal follower for life who will defend you with his 3rd eye laser beam, though this attack drains his Memory Glands quickly so there is a danger of Trooster forgetting who he is. Luckily, this can be easily remedied as long as you refresh his memory though be careful about having others influencing a Trooster with amnesia causing him to switch sides.
Once his newfound trust is broken however, Trooster unleashes all the fury he can muster & fires off his entire essence through the 3rd eye beam at whoever broke the trust so that all that’s left is a Trooster skeleton.
All is not lost even in this case, as Trooster’s spiritual essence reincarnates inside the being shot by a laser… if they’re dead, their corpse is reanimated into a temporarily zombified state which lays a new egg that becomes a Distrooster & flies away to join the other Distroosters who are all able to find each other through a hive mind process. If whoever is shot by the beam do not die, the same egg laying happens, only in a possessed as opposed to a zombified state & Trooster will forever haunt this being in their dreams.
