...I'm not sure how I feel about this after that last post and rereading this poem. I mean, at first, I didn't think it made all that much sense that a Lucario (which has fur) would glisten like diamonds, but now that you've mentioned that you have more than a strong liking for the Pokémon, my mind immediately went to the gutter. I'm not sure if you meant that, but.
Beyond that, there's a few distractions here. For one, don't capitalize the first letter of every word. It's really not necessary. On a grammatical level, you only capitalize the first word of a sentence (or line or important word, if you choose in a poem), and on a poetic level, there doesn't seem to be any need to emphasize every single word (which capitalization tends to do).
For another grammatical note, glisten. Yes, it's unusual, but as a poet, it's always a good idea to spell check and proofread. Write your poetry in a word processor (like Microsoft Word, OpenOffice, etc.) before posting to make sure your work is free of spelling errors. This really is more important in poetry than in normal stories because a poet is an artist: not a single letter, character, what-have-you in a poem should be out of place. Everything has a meaning, and if you misspell a word or misplace a punctuation mark, you're implying that there's some kind of meaning behind it that's not obvious.
As for the poem itself, if we dig my mind out of the gutter and take it for face value, it's okay. The beat is nice, and everything flows from one line to the next. I have to admit I like the rhyming scheme (for once). The entire first stanza almost had a musical quality to it.
But beyond that, it almost feels like you're putting words on paper to force the poem to rhyme. For example, if we don't consider dirty connotations, a Lucario glistening like diamonds doesn't quite make sense because, well, Lucario don't glisten. Likewise, maybe its power helps it win a battle (although that's questionable once something with a good Flamethrower comes along), but how do its good looks do the same thing? Point is, don't sacrifice meaning for the sake of getting a poem to rhyme.
Beyond that, it's not bad for a start. Just needs a bit of polishing, really.
