Faces here look like Hidehiko Sawada's work.

Probably Toru Iwazawa

The AD for this episode was Takashi Mukouda

I've been paying attention to these uploads because they're getting close to the point in time where he actually started to show some characteristics

the first two cuts and the last are def reminiscent of his early work

tragically, though, this is the last dgkb episode of pokemon

It's so surreal watching watching these early digital episodes. They were so close to finishing the first TV series, I'm surprised they didn't just wait to do the switch over to digital for AG #1?

I really enjoyed the drawings and timing on the Rockets being sent flying. There's some real oomph to it.

do you know the exact point it switched from cel to digital by any chance?

According to JP Wikipedia Episode #263: ナナコとエレキッド！ (2002.08.15) was the first digital episode.

All three of these are actually Abe (for real this time).

Jun Arai didn't animate this cut.

車内のエランやシャディク、コックピットのスレッタなど4カットほど原画致しました。

0:00 - 0:06 Kazutaka Sugiyama
0:12 - 0:15 Meka Aoratos
0:16 - 0:18 Kota Sera
0:19 - 0:20 Meka Aoratos
0:21 - 0:21 Kota Sera
0:22 - 0:27 Hideki Hamazaki
0:28 - end 猫山道節 (presumed)

If I understand the tweet correctly, Sugiyama did the first 4 cuts before the title drop, 猫山道節 is probably called Dosetsu Nekoyama, he should have done the last cut since the credits are in order.

水星OPはど頭から止めのミオリネ除いてタイトルバックのとこあたり4カットを描いていますよ

we will leave it untagged but 猫山道節 should be Michinori Chiba. I was quite sure just by the drawing alone but upon discovering a credit in 2008 under Hercules, I am almost certain.
