English Alphabet Letters in Katakana (List)

For reference, a list of the names of the English alphabet letters (ABC's) their respective katakanizations. Note that the pronunciation in romaji often doesn't match what you'd expect from English, since, well, it's not English, it's the romaji of the katakana.

See the Japanese alphabet, if you're looking for an overview of the Japanese characters.
