Theo D'Angelo is a human from Ireland. He is known for starting up a company called D'Angelo and Sons.
Theo is an average height 18-year-old male who has messy red hair. He wears a black business suit, but with orange trainers.
Theo was born and raised in Ireland, with an extremely happy family. He ended up having a sudden move to Los Angeles when he was 17. Around about a couple of weeks prior to the events of Amy vs The Future, he decided to try and open up a store, which he named D'Angelo & Sons, selling various things, acting like a goodwill store of sorts. His first customer happened to be Amy Jackson, of whom had mistaken the intentions of the store with the future she's from being virtually ruled by D'Angelo & Sons. Confused, Theo simply offered her an NES with Metroid. He had moderate success and has managed to keep the store alive.
Theo is a nice guy who is always up for giving people something to smile about. He treats customers like they're close friends.
- Theo was originally thought up to show how humble Mr. D'Angelo's business was when it started.
- There is a running joke in the Tayshaun & Amy series where RTAverse characters constantly mistake Theo's store as a disguise for Mr. D'Angelo's store.
