When you find yourself trying to remember a show (or any works) that's on the tip of your tongue but just out of reach, come here - the collective brain of the TVTropes community can probably help. Post all the details you can remember (examples help). If you're looking for a trope, head over to Trope Finder. Have general questions about tropes? Visit Ask The Tropers!
Okay, this will be a HUGE pain, but if you're positive aired on those channels, I would go through the "formerly broadcasted programs" sections of those networks on wikipedia. It'll be a lot to look through, but if it for sure was on those networks, it'll be on there! Sorry I couldn't be more help, and I hope you find it! Let us know if you do. ^^

So between 20003-2010 there was a show and i cant remember much, only that the main characters could summon monsters Pokemon/Bakuguan style and the main monster the Male protaginist coulf summon was like a Knight looking thing. I remember that the female Protaginist had a watch which was of her father who had gone missing. This is all quite vague but im desperate help!
