i've got a handful of Tennas tehee. Though I do have an idea on how some of them would react.
ESPECIALLY my main son Tennaryox (or DeltaRoads Tenna as I would say prior to the name drop). He's very intrigued by the weird, and is especially attracted to learning more about Tennas with peculiar quirks (whether it's because of some monstrous qualities they have or the situation being so out there they seem like a high contrast compared to other Tennas). It's kinda why I personally see him as being besties with another one of my Tennas (Sapphire, aka the spider one lol). Though he is always up for interacting regardless. He's like a curious puppy when it comes to meeting new Tennas.
But in general, I like to think the DeltaRoads Archangels are naturally attracted to the weird because of their existence. Tennaryox is just the most notable since he is more likely to be seen outside of New Wirral via dimension hopping stuff they can do.
As for the other Tennas I got, I have a few words on em (putting it under the cut cause this post is gonna get fairly long I think)
Sapphire and Arc would approach with curiosity too. Though Sapphire's would be moreso the kind a predator would have when stalking prey (but without any ill will, for the most part) and Arc is just excited to learn more about other places beyond the arcade. Sapphire would probably be more calculating and careful with his words when with other Tennas, whilst Arc just says stuff because homie has no filter and is a bit of a dumbass. Similar reactions separate approaches y'know.
Adtonio (AddiTenna) would be estatic. Like "holy shit I'm related to other CRTs across other timelines??? Fuck yeah." Dude is in deep denial about being an Addison woop, so seeing the TV Tennas makes that bit of him spark with joy. Though he would be hesitant around any other Addison Tennas if they crossed paths. Hell, even swap Spamtons that still look like his Addison self will get the side eye. Just, do not let AddiTenna near any Addison for everyone's sake... he'd probably throw a fit if left for too long.
Antonio (SPM-1997) would be rightfully confused. Though would also have so many questions to try and then share about the existence of alternate worlds on his lil podcast thingy. Bro is just a human, wouldn't you also have a similar reaction if you learned you are inhuman in other worlds?
Lastly for this yap is that swap Tenna I got (I like to call him Umbra because of the AU name). He would try to get whatever he can from other Tennas to reignite that shining spark he lost oh so long ago. tryna play it off cool before going a bit manic and with a plan held together with tape and a few strands of wet pasta. but afterwards he would just try to get some sort of connection going.
hope that's a sufficient answer <:3
(teehee, I see you from that talk we had elsewhere regarding something similar 🫵)
