Question: Which artist worked for the series the longest? Passage 1:The main feud heading into One Night Stand on the Raw brand was between Triple H and Randy Orton over the WWE Championship. At Backlash, a Fatal-Four Way Elimination match took place for the WWE Championship. The contestants were Orton, Triple H, John Cena and John "Bradshaw" Layfield (JBL). Triple H won the match after last eliminating Orton to win the WWE title. At Judgment Day, Triple H defended the WWE Championship against Orton in a Steel cage match. Triple H won the match after a Pedigree to retain the title. On the May 19 episode of Raw, General Manager William Regal booked a tag team match between Orton and JBL against Cena and Triple H. If Orton and JBL won, they would have received re-matches against Triple H and Cena, respectively, at One Night Stand in an extreme match of their choosing. If Cena and Triple H had won, however, then the pair would have faced each other for the WWE Championship, with Regal choosing the match type. After Orton and JBL won the tag team match, Orton announced that he and Triple H would compete in a Last Man Standing match for the WWE Championship at One Night Stand. JBL announced that he and Cena would compete in a First Blood match at One Night Stand.
 Passage 2:Lake Malawi is noted for being the site of evolutionary radiations among several groups of animals, most notably cichlid fish. There are at least 700 cichlid species in Lake Malawi, with some estimating that the actual figure is as high as 1,000 species. The actual number is labelled with some uncertainty because of the many undescribed species and the extreme variation among some species, making the task of delimiting them very complex. Except for four species (Astatotilapia calliptera, Coptodon rendalli, Oreochromis shiranus and Serranochromis robustus), all cichlids in the lake are endemic to the Malawi system, which also includes nearby smaller Lake Malombe and the upper Shire River. Many of these have become popular among aquarium owners due to their bright colors. Recreating a Lake Malawi biotope to host cichlids became quite popular in the aquarium hobby. Most Malawi cichlids are found in relatively shallow coastal waters, but Diplotaxodon has been recorded down to depths of and several (especially Diplotaxodon, Rhamphochromis and Copadichromis quadrimaculatus) are known from pelagic waters.
 Passage 3:He was spun off into his own title, the 1968–74 series Sub-Mariner. The super-villain Tiger Shark was introduced in issue #5 by writer Roy Thomas and artist John Buscema and the super-hero Stingray in issue #19 by Thomas and Bill Everett. Some of the later issues of this Sub-Mariner series are notable for having been written and drawn by the character's creator, Bill Everett, shortly before his death; as well, they reintroduced a now-older Namora, and introduced her daughter, Namorita Prentiss. By now more of a reluctant superhero "the Sub-Mariner was perfect for the Marvel Age of angst-ridden protagonists. Noble yet misunderstood, powerful yet thwarted ... [he was] portrayed as a regal monarch – a king without a country." The final issue, #72 (Sept. 1974), was written by Steve Skeates and featured an unofficial intercompany crossover with the last issue of DC Comics' Aquaman series. A five- to six-page backup feature, "Tales of Atlantis", chronicling the undersea kingdom from its ancient origins, appeared in issues #62–66 (June–Oct. 1973), written by Gerber, with penciling by Howard Chaykin and later Jim Mooney. After the cancellation of Sub-Mariner, Namor co-starred with Doctor Doom in the Super-Villain Team-Up series. The series suffered from mediocre sales due to its lack of a stable creative team, and following issue #13 Namor was dropped from the co-star spot.
