Each time we see future Ben he's different because Ben meeting his future self changes his future... (Like how if you saw yourself get hit by a car in the future, when you arrived at that point I'm time naturally you would know the car is coming and things would play out differently.) Ultimate alien series Ben was up himself and treated being a hero more like being a celebrity so his future self naturally has abilities that reflect that, letting his CELEBRITY face remain seeable at all times rather than the anonymity the watch provides with on demand alien disguises. Even his name "Ultimate Ben" is egotistical.

Whenever we open a can of tuna we drain the can into a bowl, split it in two (one for each cat we have) and then dilute it a bit with water and give it to the cats. Our cats go crazy for it.
