Oblivion's Adoring Fan and his chronically bad hairstyle are in Starfield

If you ever became Grand Champion in the combat arena in The Elder Scrolls IV: Oblivion, then you will recognise the little cone-headed gimp who made a surprise cameo in tonight's Starfield deep dive, streamed as part of the Xbox Games Showcase for not-E3. In the case of the upcoming space-themed mega-RPG, he'll attach to your character if you choose the trait Hero Worshipped. He still has stupid hair in Starfield, too.

In Oblivion he just says you're great and will offer to follow you around (if you accept he will become a companion, but he's useless because he mostly runs away if combat happens). I personally think that AF's memetic qualities are few, but his blank grin in his meaty, wide face do lodge in the memory. There's something a bit Mr. Blobby about him, almost... I hate him, is what I'm saying. I don't think he's funny or cute. But apparently I am in the bastard minority. Bethesda did get a bit knowingly self-referential for the showcase at times, and I'll be keeping an eye on that going forward. Companies aren't supposed to be self-aware. That's how we get Skynet, isn't it?

Anyway, it sounds like Adoring Fan will be just a tad more useful in Starfield, as he will "join your ship's crew and give you gifts", but on the other hand he's only good at Scavenging, Weight Lifting and Concealment, so the gifts will probably be shit. Also the trait screen says he'll "show up randomly", which means he probably uses the Concealment skill to jump-scare you with his triangular head, like a big yellow Toblerone.

On the plus side, it does look like you can shoot him with both barrels in the back if he does turn out to be too creepy and/or annoying, so that's nice. You can see my man in the video above at about the 15 minute
