How do you define Shard Bullshit™?
@YoRHa_42s got it pretty much exactly;
To me there are two kinds of Crossovers for Worm, powerwise;
An Alt!Power is when QA or some other Shard does some bullshit to unknowingly emulate some fiction out there.
This power is more often than not, not OOC at all and is subject to all the usual Shard Bullshit such as Power Nullifiers, Trumps, Shards themselves such as Administrators and other Vital Shards, Thinker Headaches, Precogs, Jack Slash and Cuntessa screwing you over.
This seems to me when an author is writing a power that seems interesting to use in Worm without actually using anything but the cosmetic appearance of the power.
A prime example is that Ben 10 cross where it's explicitly been stated that the OC has triggered with a Changer power that works on Shard Bullshit but just so happens to have forms that look and have similar strengths to Ben 10 aliens.
The other kind of Alt!Power is more of an AU thing than just changing or introducing a novel power expression based on some work of fiction out there.
Here, the character in question did NOT trigger with a Shard Power at all; via whatever reason the author is welcome to use, whatever power from that fiction is used completely works on the physics of that system, implying that it exists and making it an actual crossover.
For example, there's more than a few Ben 10 crosses that have either an SI, Taylor or an OC have an/the Omnitrix or any of its variations end up on their wrist. This means that their Grey Matters tech isn't blackboxed, that their Alien X's are probably never going to show up in the story at all for balance reasons(🤣), etc.
[X] In the thick of Action
Here's my prediction;
This will lead to how our powers develop:
Remote controlled Giant may lead us to be the stereotypical Worm Master with 0 personal strength and relying on their Minion. We MAY eventually be able to interact with and give orders mentally at some point, but the OP may end up having us face a threat that would affect us personally, for the sake of story conflict. Taylor may never really get that he's sapient due to heir distance.
However, my hope for the Action vote is that we may develop a bit like an actual Magus a bit. Certainly we aren't goin to slack on physical training when we may have to run around and dodge stuff when we're in the thick of the action, but maybe us nearly getting hurt by a threat would lead Herc to do some NP worthy bullshit or other things that would make Taytay realize that he's not just a projection, but actually sapient.
