Tucker's pretty sure that the day of the accident they walk out of the real world and into a Sci-Fi movie. Not allot since has proven him wrong. He really didn't understand why Danny wouldn't a lest consider telling his parents but eventually Tucker grew to like being in on the Secret. It was way more fun (most of the time) and stop bring it up.
Yes he grew jealous but who wouldn't. It could have easily been him that day. Why did Danny get all the cool powers? So Tucker made the wish. While he blamed his actions on Desire a small part of him would from then on question how much was really him and how much was her. Latter he would admit that Tucker Phantom just didn't have the same ring to it and try not to be so hard on Danny.
Feeling like a sidekick sucked. He knew Danny didn't mean to but Tucker often felt like a third wheel to the two kickass love birds. It never lasted but sometimes he just couldn't help thinking of himself as plain old Tucker Foaly, no powers, no training, no ridiculous amount of a cult knowledge, just a plain old computer geek.
On the other hand the ghost hunting was an adrenaline rush. There was nothing more empowering then hacking a ghost system and making them do what he typed. Sure there were bad times and he still argued that the thermos drop was not his fault. He was not clumsy thank you very much.
Keeping it from his parent was the hardest part he always felt bad when they believed his lies because they trusted him. It was still easier that what the others had to deal with at home.
Finding out about Dan was a both terrifying and a relief. Terrifying because Danny might actually turn on the world. Relief because it wasn't just him who had those urges when he had powers.
Jazz's addition was surprisingly welcome. She had taken any focus off his past mistakes. He was never that bad. She also provided someone he could talk to about his envy with feeling like the worst friend in the world. She understood called it Ghost envy said she sometime felt the same way when her parent seemed to care more about ghosts than her and Danny. Tucker had never thought about it that may.
So maybe he was prone to going a bit power mad not like Sam was much better. He had to be careful with what he said for months after to avoid setting anyone off. That was not fun. Danny and Sam where surprisingly forgiving of the whole debacle.
When Danny gave up his powers he was mad. Danny was throwing away the gifts Tucker want like it was nothing. It felt like Danny was making everything they had done since the accident worthless. Ya he was mad. He calmed down latter when Danny returned with his powers and a plan. He got his reward in the end the recognition. He was Mayor that was cool. Maybe being plain old tucker Foaly wasn't too bad after all.
Tucker was a lot harder to write than the others. I tried not to make it seem like i was bashing him.
