Author's Note: Thanks once again for your comments and support! In answer to requests for additions – these acrostics are based on characters in the first movie, so neither Bishop nor Karai apply. Sorry. However, for anyone interested, here is my take on Shredder, aka Oroku Saki.
Saki was once a noble ninja; courageous, loyal and honourable
His closest friend Hamato Yoshi, linked by rivalry amicable
Rivals as the foremost kage, then rivals for the love of Tang Shen
End of friendship, end of honour, drowned in bitter jealousy
Deserting honour killed his love – none could have her if not he;
Deserting Clan he killed his old friend, hating him for winning her;
Ending thus his former life, ending thus his former name; he became another man
Rising from the bitter ashes: the Shredder and his evil Foot Clan.
